How to change payroll pay period? I accidentally created last month's (April) payroll for this month's period (May).

It's nice to have you here today, @naya0728. Let's sort this out and correct the pay period on your employees' paychecks in QuickBooks Online (QBO).

To change the pay period, delete or void the paycheck before recreating a new one. Deleting a paycheck removes it from your payroll. On the other hand, voiding it modifies the paycheck dollar amount to zero. However, these options depend on your processing time.

To do that:

1. Go to the Payroll section and select Employees.
2. Click Paycheck list.
3. Select the dropdown icon in the Action column and choose between Delete and Void.

Once done, run payroll again with the correct pay period. 

Here's an article to learn more: Edit, delete, or void employee paychecks.

Furthermore, your employees can access their own paychecks and W-2s online by inviting them to QuickBooks Workforce.

I'll leave this thread open in case you have any follow-up concerns about changing a paycheck's pay period. We're always around to offer assistance. Take care.
